How load data into OLAP Manager from a excel pre-loaded in File Manager?

I can load my data (a excel, .xlsx, with 8000 registers) in the File Manager, but, how load this data into the OLAP Manager?
Testing, i achieve create a cube with dimensions (in OLAP Manager), however, the dimensions are empty and cannot seek a option that allow me load my data into him.

I don't think you can use File manager to transfer data from .xlsx files into Jedox OLAP cubes.

You could try the following:
Export the data from you .xlsx file into .csv or .xml format, and use the ETL load the data into a cube. The basic process for ETL is
1. Create a Connection->File->Type: File or xmlFile
2. Create an Extract to get dimensions and measure aligned.
3. Create a Load task to load from the Extract and put into your cube.
4. Create a Job to run the Load task.
